Dependencies

The page lists the prerequisite packages that need to be installed on the different platforms to be able to configure, build and run ROOT.

The table of content can be used to quickly jump to your operating system.

MacOS

  • Xcode developer package: Xcode is found on the Mac App store. Install command line tools through the XCode preferences and/or running in a terminal xcode-select --install

Windows

ROOT 6

  • CMake (version >= 16.3)
  • Microsoft Visual C++ (ROOT6 requires at least Visual Studio 2019 version 16.1). The Community version is free, fully-featured for students, open-source contributors, and individuals.
  • Python (ROOT6 requires version >= 2.7)

ROOT 5 (deprecated)

If you are using Windows make sure you have installed Microsoft Visual C++ (e.g., the no-cost edition) plus CMake. The CMake build will work directly without the need to install cygwin as it was required previously before the adaption of CMake.
